Title: Overhead projector
Inventor: ONO TAIZO
IPC: G03B21/134
Filed: 1991-03-07
Abstract: PURPOSE:To prevent an overhead projector(OHP) original from rising at a projecting time and to clearly project and display it all the corners thereof by providing a mirror-Fresnel lens on an original platen cover. CONSTITUTION:The image of the original 15 placed on an original platen 14 is read by moving the platen 14 and an image signal read by a read part 17 is recorded on a recording sheet 20 by a recording means 19. Then, the mirror- Fresnel lens 21 is installed on the smooth upper surface of the original platen cover 16. Since the lens 21 is positioned just under a projecting lens 24 even when the platen 14 is not moved, it functions as a reflection type OHP as it is. Besides, since the surface of the cover 16 is flat extending over the whole surface, the OHP original 26 does not rise even when it is larger than the lens 21 in the case that it is placed on the surface of the lens 21.

Title: Scribing method of semiconductor wafer
Inventor: SUZUKI MASATO
IPC: H01L21/301
Filed: 1988-02-26
Abstract: PURPOSE:To block cracks by trenches and prevent an adverse influence on an electrode pad and the like, even if cracks generate in a pellet, by arranging the trenches on both sides of a scribe line in addition to the scribe line, and scribing a wafer along the scribe line between the trenches. CONSTITUTION:A wafer 1 is scribed along a scribe line 2 between adjacent trenches 5, 5. A pellet 3 is constituted of, e.g., silicon single crystal substrate. In this pellet main body 3', many circuit elements are formed, and a circuit function is assigned. An electrode pad 3'' is arranged on the peripheral part of the pellet main body 3 '. When the wafer 1 is scribed and the pellet 3 is made, cracks 4 may generate on the peripheral part of the pellet 3, at the time of scribing. But since the trenches 5 exist and act as stoppers for the cracks, the pellet main body 3' is not affected by the cracks. Even if cracks 4 generate when the pellet 3 is sucked by a collet, and fixed on a lead-frame and the like, the adverse influence on the pellet main body 3 ' can be prevented by the existence of the trenches 5.

IPC: H03L7/14
Filed: 1984-03-06
Abstract: PURPOSE:To obtain fast synchronism characteristics with a simple additional circuit by interposing a rectangular wave oscillator and a switch between a phase comparator and an LPF. CONSTITUTION:A switch 6 sends the output of the phase comparator 7 to the LPF2 with a switch control signal 8 in the presence of an input signal 5, and a phase locked circuit is formed. When the input signal is absent, on the other hand, the switch 6 sends the output signal of the rectangular wave oscillator 9 to the LPF2 with a control signal 8 and a voltage-controlled oscillator 4 outputs a frequency-modulated signal which is determined by the output voltage of the oscillator 9. Then, fast synchronism characteristics are obtained by equalizing the mean output frequency of the voltage-controlled oscillator 4 to the input signal 5 or setting an error small. The rectangular wave oscillation circuit 9 is formed of a simple circuit. Thus, the fast synchronism characteristics are obtained with the simple additional circuit.

IPC: H04H40/72
Filed: 1988-02-24
Abstract: PURPOSE:To reduce noise of a voice difference signal channel at FM demodulation and to improve the sensitivity by reducing a subcarrier frequency of a difference component multiplex signal. CONSTITUTION:An output of a multiplier circuit 12 is led to a band pass filter 13, from which a difference frequency component is obtained. The output of the filter 13 is fed to a carrier elimination circuit 14, from which only a side band is obtained. The component comprising the side band only is fed to a multiplier circuit 15 to form the sum and difference components with an output of a carrier oscillator fq 16 and a band pass filter 17 extracts a component lower than the upper side band by the frequency fq and a component higher than the upper side and by the frequency fq around the carrier frequency. Then the carrier component eliminated by the carrier elimination circuit 14 is added by an adder circuit 18, shaped by an amplitude limiter 19 and the result is fed to an FM demodulation circuit 20. Thus, the voice subcarrier is reduced to 2fp-fq from 2fp(=38kHz). In case of fq=fp, the relation of 2omegap-omegaq=omegap exists thereby attaining noise reduction.

Title: Surface acoustic wave device and manufacture of the device
Inventor: AKIYAMA OSAMU
IPC: H03H9/145
Filed: 1992-02-28
Abstract: PURPOSE:To improve characteristics by suppressing the bidirectional loss of the surface acoustic wave(SAW) device and reflection loss caused by the discontinuity of an IDT. CONSTITUTION:After forming a metal thin film on a piezoelectric substrate 3, one side face of an electrode finger pattern is inclined or made into a circular arc by executing both of isotropic etching and anisotropic etaching to the same pattern in two times of photolithography processes. The opposite side face is made almost perpendicular to the substrate. Then, SAW 5 are reflected at the terminal part of input/output IDT 1 and 2 because of discontinuity caused by the quantity adding effects of the IDT. Since this reflection coefficient is reduced in the case of smoothly raising the terminal part of the IDT and enlarged in the case of sharply raising it, loss can be considerably reduced by unidirectionally propagating SAW with the asymmetrical cross sectional shape of an electrode finger.
